摘要：

This paper identifies the different friction regimes encountered in elastohydrodynamic lubricated point contacts using a quantitative, physics-based approach. The idea is to link different traction regimes to dimensionless numbers and identify ranges of those numbers where a given regime is encountered or dominates the friction response of the contact. A numerical investigation of traction in point contacts lubricated with a typical mineral oil is employed. The measured thermo-physical properties of the oil are used without any modification to force agreement with experiments. The authors propose four friction regimes delimited by the combined values of three dimensionless parameters. (C) 2012 Elsevier Ltd. All rights reserved.
